Central nervous system tuberculosis following delayed and initially missed lung miliary tuberculosis: a case report

Central nervous system (CNS) tuberculosis includes three clinical entities: tuberculous meningitis, intracranial tuberculoma, and spinal tuberculous arachnoiditis. All three categories are encountered frequently in regions of the world where the incidence of TB is high. Meningeal tuberculosis is a medical emergency: it is the most severe, lethal and disabling form of tuberculosis. Early diagnosis and treatment can be lifesaving. Even, in developed countries the diagnosis of tuberculous meningitis is difficult, frequently delayed or missed, and is often not microbiologically confirmed. Here I report a case of miliary tuberculosis, in a patient with diabetes mellitus and chronic kidney disease, but without HIV infection. Although the patient had regular contact with healthcare staff (hemodialysis), miliary tuberculosis diagnosis was considerably delayed. This patient, subsequently evolved into tuberculous meningitis. In spite of quadruple anti-tuberculosis treatment, corticosteroids, and general supportive care, this case resulted in death.
